摘 要
机械部件的高效运行和长寿命依赖于合理的润滑系统设计与磨损控制，而润滑不足或不当会导致严重的性能下降和设备故障。本研究以提高机械部件润滑效果、降低磨损为目标，针对现有润滑系统设计中的不足展开深入分析。通过理论建模与实验验证相结合的方法，研究了不同工况下润滑剂流动特性及其对摩擦副表面的影响，并提出了一种基于多物理场耦合的优化润滑系统设计方案。该方案综合考虑了流体动力学、热传导及材料磨损机制，能够显著改善润滑分布均匀性并延长部件使用寿命。研究结果表明，优化后的润滑系统可使关键部位的磨损率降低约35%，同时在高负载和高温条件下表现出更稳定的性能。

Abstract
The efficient operation and long life of mechanical parts depend on reasonable lubrication system design and wear control, while insufficient or improper lubrication can lead to serious performance degradation and equipment failure. The study aims to improve the lubrication effect of mechanical parts and reduce wear, and conducts in-depth analysis on the deficiencies of the existing lubrication system design. By combining theoretical modeling and experimental verification, the lubricant flow characteristics and their effects on friction subsurfaces under different working conditions are studied, and a design scheme of optimized lubrication system based on multiple physical field coupling is proposed. This scheme comprehensively considers the fluid dynamics, thermal conduction and material wear mechanism, which can significantly improve the uniformity of lubrication distribution and extend the service life of the components. The results show that the optimized lubrication system can reduce the wear rate of key parts by about 35%, while showing more stable performance under high load and high temperature conditions.
